[0002] In paper mill, a large amount of waste paper pulp will be produced every day, and in the process of treating these waste paper pulp, the paper pulp needs to be solid-liquid separated to separate the solid impurities in the paper pulp. In the prior art, the device for solid-liquid separation of waste water, such as the utility model patent with patent application number 201921915139.3, mainly consists of a box body, a filter cartridge and a conveying pipe, etc., and the filter cartridge is installed in the box body. When the device is used for solid-liquid separation of waste water, the waste water is added into the filter cartridge, and then the waste water is filtered by the filter cartridge and enters the box body, and the solid impurities in the waste water are left in the filter cartridge, thereby realizing solid-liquid separation. The inventor believes that the device has the following problems in use: when the device is used for solid-liquid separation of waste water, it cannot discharge the separated solid impurities while performing solid-liquid separation of waste water, which has poor continuity, is inconvenient to use and has low work efficiency. Therefore, a dehydration device is needed that can discharge solid impurities while performing solid-liquid separation. SUMMARY

[0003] To solve the above technical problems, the utility model provides a paper pulp squeezing dehydration separation equipment that can collect the solid impurities in the paper pulp into the collecting mechanism while performing solid-liquid separation of the paper pulp, has high continuity, is convenient to use and has high practicability.

[0004] This utility model discloses a pulp pressing and dewatering separation device, comprising a base plate, a water tank, a cylinder, and an inlet pipe. The water tank is fixedly installed on the upper part of the base plate, and the cylinder is fixedly installed on the water tank. The cylinder contains a chamber, and an opening is provided at the right end of the cylinder, which is located to the right of the water tank. The cylinder has multiple sets of filter holes communicating with the chamber. The inlet pipe is installed on the left side of the cylinder and communicates with it. The water tank contains a cavity. The device also includes a pressing mechanism and a collecting mechanism. The cylinder is conical in shape and is installed at an angle on the water tank, with the left end of the cylinder lower than the right end. A filter cloth is provided on the outer wall of the cylinder. The pressing mechanism is installed on the cylinder and has a pressing and conveying function. The collecting mechanism… Installed on the right side of the water tank, the collection mechanism has a collection function. When the pulp is separated into solid and liquid components, the pulp is added to the chamber of the cylinder through the water inlet pipe. Then, the pulp is conveyed to the right in the cylinder by the squeezing mechanism while being squeezed. The water in the pulp falls into the chamber of the water tank through multiple filter holes on the cylinder. The solid impurities in the pulp continue to be conveyed to the right in the cylinder and fall into the collection mechanism through the opening at the right end of the cylinder for collection. The water in the pulp falls into the cavity of the water tank through the filter holes on the cylinder. It can push the solid impurities in the pulp into the collection mechanism for collection while performing solid-liquid separation of the pulp. It has high continuity, is convenient to use, and has high practicality.

[0005] Preferably, the extrusion mechanism includes a motor, a rotating shaft, and spiral blades. The motor is fixedly installed at the left end of the cylinder, the rotating shaft is rotatably installed on the cylinder, and the left end of the rotating shaft is connected to the output end of the motor. The spiral blades are fixedly installed on the rotating shaft, and the diameter of the spiral blades gradually decreases from left to right. When the pulp enters the chamber of the cylinder through the water inlet pipe, the motor is turned on, and the motor causes the spiral blades to rotate through the rotating shaft. During the rotation, the spiral blades push the pulp in the chamber of the cylinder to the right. Since the diameter of the spiral blades gradually decreases from left to right, the spiral blades continuously extrude and compress the pulp while conveying it to the right, causing the water in the pulp to enter the water tank through the filter holes on the cylinder, and the solid impurities in the pulp to enter the collection mechanism for collection through the opening at the right end of the cylinder; this improves convenience.

[0006] Preferably, the collection mechanism includes a collection box, a filter plate, a return pipe, and a lifting mechanism. The collection box is fixedly installed at the right end of the water tank. A collection chamber is provided inside the collection box. The filter plate is slidably installed inside the collection chamber of the collection box. A filter cloth is provided on the upper end of the filter plate, and multiple vertically connected drain holes are provided on the filter plate. The upper end of the return pipe is connected to the lower end of the collection chamber of the collection box, and the lower end of the return pipe is connected to the cavity of the water tank. A valve is provided on the return pipe. The filter plate is installed on the lifting mechanism, and the collection box is located below the right end of the cylinder. When the cylinder... Solid impurities are discharged through the opening at the right end of the cylinder and fall into the collection box. Then, the solid impurities fall onto the filter plate to drain again. The residual water in the solid impurities then falls through the filter plate into the lower part of the collection chamber of the collection box. Then, the valve on the return pipe is opened to allow the water in the lower part of the collection box to flow into the water tank through the return pipe. When it is necessary to collect solid impurities on the upper part of the filter plate, the lifting mechanism is opened to raise the filter plate, which in turn raises the solid impurities and brings them closer to the opening at the upper end of the collection box, making it easier to collect the solid impurities.

[0007] Preferably, the lifting mechanism includes a hydraulic cylinder and a push rod. The hydraulic cylinder is fixedly mounted on the base plate, and the push rod is slidably mounted on the collection box. The lower end of the push rod is connected to the output end of the hydraulic cylinder, and the filter plate is fixedly mounted on the upper end of the push rod. When adjusting the height of the filter plate, the hydraulic cylinder is opened, and the hydraulic cylinder drives the filter plate to adjust its height through the return pipe. This facilitates the adjustment of the filter plate height.

[0008] Preferably, it also includes a vacuum pump, a suction pipe, and an exhaust pipe. The vacuum pump is fixedly mounted on the base plate. The input end of the vacuum pump is connected to the lower part of the collection chamber of the collection box. The suction pipe is located below the filter plate and is equipped with a valve. The output end of the vacuum pump is equipped with an exhaust pipe. When solid impurities drain water on the filter plate, the valve on the return pipe is closed, the valve on the suction pipe is opened, and then the vacuum pump is turned on to reduce the pressure in the lower part of the collection chamber of the collection box, thereby promoting the dehydration speed of solid impurities on the filter plate and improving convenience.

[0009] Preferably, it also includes a baffle plate, which is obliquely and fixedly installed at the lower part of the collection chamber of the collection box, and the baffle plate is located above the air extraction pipe; the above arrangement prevents water falling from the filter plate from falling into the air extraction pipe, thereby improving reliability.

The water tank 2 is fixedly installed on the upper end of the base plate 1, and the cylinder 3 is fixedly installed on the water tank 2. The cylinder 3 has a chamber inside, and an opening is provided at the right end of the cylinder 3, which is located to the right of the water tank 2. The cylinder 3 has multiple sets of filter holes communicating with the chamber. The water inlet pipe 4 is installed on the left side of the cylinder 3 and communicates with the cylinder 3. The water tank 2 has a cavity inside. The cylinder 3 is conical in shape and is installed at an angle on the water tank 2. The left end of the cylinder 3 is lower than the right end of the cylinder 3. A filter cloth is provided on the outer wall of the cylinder 3. The pressing mechanism is installed on the cylinder 3 and has the function of pressing and conveying. Yes, the collection mechanism is installed on the right side of the water tank 2 and has a collection function. When the pulp is separated into solid and liquid, the pulp is added into the cavity of the cylinder 3 through the water inlet pipe 4. Then, the pulp is conveyed to the right in the cylinder 3 by the squeezing mechanism while being squeezed. The water in the pulp falls into the cavity of the water tank 2 through multiple filter holes on the cylinder 3. The solid impurities in the pulp continue to be conveyed to the right in the cylinder 3 and fall into the collection mechanism through the opening at the right end of the cylinder 3 for collection.

The left end of the rotating shaft 6 is connected to the output end of the motor 5. The spiral blade 7 is fixedly installed on the rotating shaft 6, and the diameter of the spiral blade 7 gradually decreases from left to right. When the pulp enters the chamber of the cylinder 3 through the water inlet pipe 4, the motor 5 is turned on. The motor 5 causes the spiral blade 7 to rotate through the rotating shaft 6. During the rotation, the spiral blade 7 pushes the pulp in the chamber of the cylinder 3 to the right. Since the diameter of the spiral blade 7 gradually decreases from left to right, the spiral blade 7 continuously extrudes the pulp while conveying it to the right, causing the water in the pulp to enter the water tank 2 through the filter holes on the cylinder 3. Solid impurities in the pulp enter the collection mechanism through the opening at the right end of the cylinder 3 for collection, thus improving convenience.

[0022] like Figure 2 , Figure 3 and Figure 5The collection mechanism includes a collection box 8, a filter plate 9, a return pipe 10, and a lifting mechanism.

After solid impurities in body 3 are discharged through the opening at the right end of body 3, they fall into collection box 8. Then, the solid impurities fall onto filter plate 9 to drain again. The residual water in the solid impurities then falls through filter plate 9 into the lower part of collection chamber of collection box 8. Then, the valve on return pipe 10 is opened, allowing the water in the lower part of collection box 8 to flow into water tank 2 through return pipe 10. When it is necessary to collect solid impurities at the upper end of filter plate 9, the lifting mechanism is opened to raise filter plate 9, thereby raising the solid impurities and bringing them closer to the opening at the upper end of collection box 8, which facilitates the collection of solid impurities.

[0023] like Figure 6 The lifting mechanism includes a hydraulic cylinder 11 and a push rod 12.

The lower end of the push rod 12 is connected to the output end of the hydraulic cylinder 11, and the filter plate 9 is fixedly installed on the upper end of the push rod 12. When adjusting the height of the filter plate 9, the hydraulic cylinder 11 is opened, and the hydraulic cylinder 11 drives the filter plate 9 to adjust its height through the return pipe 10. This facilitates the adjustment of the height of the filter plate 9.
